� � " . OF'�EC � 9� V 70 '��1�� '/l l I N O\Y October 31, 2000 WATER MANAGEMENT MEMORANDUM NO. 2000 - 11 MEMORANDUM TO: Honorable Mayor and City Council FROM: Steve Garman, City Manager Stephen P. Swanson, P. E., Acting Director of Water Management�� Keith D. Alexander, Lake Manager /� SUBJECT: Illinois State Water Survey Lake Decatur Watershed Monitoring Contract The attached Resolution is for the approval of a contract with the Illinois State Water Survey to continue water quality monitoring from December 1, 2000, through November 30, 2001, in the �', Lake Decatur Watershed for the eighth consecutive year. It also provides for the reporting and 'i comparison of these findings with the first seven years of monitoring, with a report to be I delivered no later than January 31, 2002. This contract is significantly different than previous monitoring contracts due to the ' impending installation of nitrate removal equipment at the South Water Treatment Plant. Due to the equipment installation, watershed monitoring of nitrate-nitrogen has been significantly reduced while several other important water quality parameters have been added. The parameters are pH, arsenic, boron, sulfur and nonvolatile organic carbon. The monitoring of these parameters on a biweekly basis will enable the City to identify and react to Sangamon River water quality changes in an expedient and cost effective manner. The proposed contract cost is $36,261. Last year's contract cost was $36,036. It was originally recommended that $25,000 in Water Capital funds be allocated for this year's monitoring contract. This was based on the anticipated scope of work involving the monitoring of nitrate-nitrogen only. Current City staff believes that monitoring expenditures equivalent to last year are necessary to protect Decatur's public water supply, and recommend that the Council approve the enclosed resolution and contract.
